Design of Interfaces of Supramolecular Polymers for Controlling Hierarchical Structures and Functions

Supramolecular polymers are molecular assemblies in which molecules are regularly arranged in one or two dimensions via non-covalent bonds. Supramolecular polymerization has attracted the interest of many researchers as an important technology for the bottom-up construction of nanomaterials. Regarding material applications, the reversibility of assembly and dissociation is expected to lead to self-healing and stimulus-responsive materials. In addition, as various functional groups can be attached to their interfaces, supramolecular polymers can be used as scaffold materials for cell culture in regenerative medicine and photocatalytic reactions. This review focuses on recent research addressing interfaces of supramolecular polymers. We discuss the design of interfaces of supramolecular polymers and the construction of higher-order structures. Additionally, we cover biomaterials, optoelectronic materials, and hybrid materials that utilize functionalized interfaces on supramolecular polymers.
